Product information

Description

The FSP ST 1500 Line-Interactive Uninterruptible Power Supply is designed to provide reliable power backup and surge protection for sensitive electronic equipment, workstations, and servers. Delivering an output capacity of 1.5 kVA and 900 W, this tower UPS features a pure sine waveform and automatic voltage regulation to stabilize incoming power fluctuations. With eight IEC outlets, active cooling, and a USB Type-B communication port, it ensures continuous operation and data integrity during unexpected power outages.

Advantages

This uninterruptible power supply utilizes a line-interactive topology along with a pure sine waveform output, making it safe for sensitive electronics with active PFC power supplies. The inclusion of automatic voltage regulation allows the unit to correct high and low voltage conditions without switching to battery power, thereby extending battery life. The robust tower design incorporates active cooling to maintain optimal operating temperatures under load, while the eight IEC outlets provide ample connection options for multiple devices.

Suitable for

  • Home offices and small business workstations
  • Small servers and network attached storage devices
  • Peripherals and networking equipment
  • Sensitive audio and video electronics

When it may not be suitable

This uninterruptible power supply may not be suitable for large-scale enterprise server racks that require rack-mounted power units or high-capacity scalable battery systems. Additionally, devices exceeding the 900 W maximum power consumption limit cannot be supported.

Key specifications

  • UPS topology: Line-Interactive
  • Output power capacity: 1.5 kVA
  • Output power: 900 W
  • Waveform: Sine
  • Form factor: Tower
  • Input operation voltage range: 81 V to 270 V
  • Input frequency: 50/60 Hz
  • Outlets: 8 IEC outlets
  • Connectivity: USB Type-B port
  • Color: Black

How to use

Place the tower UPS on a flat, stable surface in a well-ventilated area near the devices you want to protect. Connect the power cord to a standard wall outlet and allow the internal battery to charge fully before initial operation. Plug your critical equipment into the designated IEC outlets on the rear panel. Connect the USB Type-B cable to your computer if you wish to monitor power status and manage shutdown settings using compatible software. Press the power button to turn on the unit and activate backup protection.

What to consider before purchase

  • Verify that your total connected equipment load does not exceed 900 W
  • Check that your devices use IEC power connections or appropriate adapter cables
  • Ensure adequate physical space near your workstation for the tower form factor

Usage recommendations

Position the UPS in a dry location away from direct sunlight and heat sources, and periodically test the battery backup functionality to ensure reliable performance during a power failure.
